Excessive pig manure application probably degrades arable soil quality in some intensive pig farming areas. The responses of the nematode community to dosages of pig manure were investigated in Ferric Acrisols under 3-season peanut monoculture. Varying dosages of manure (1.75, 3.5, 7, 14 and 28 t·ha(-1)·yr(-1)) in combination with chemical fertilizer were applied to field plots, and chemical fertilizer alone was also applied as a control. With increasing manure application, the abundance of bacterivores and omnivores-predators increased, the abundance of plant parasites decreased, and fungivores abundance exhibited hump-shaped variation...

Lipoxygenase (LOX) genes are widely distributed in plants and play crucial roles in resistance to biotic and abiotic stress. Although they have been characterized in various plants, little is known about the evolution of legume LOX genes. In this study, we identified 122 full-length LOX genes in Arachis duranensis, Arachis ipaënsis, Cajanus cajan, Cicer arietinum, Glycine max, Lotus japonicus and Medicago truncatula. In total, 64 orthologous and 36 paralogous genes were identified. The full-length, polycystin-1, lipoxygenase, alpha-toxin (PLAT) and lipoxygenase domain sequences from orthologous and paralogous genes exhibited a signature of purifying selection...

To test the hypothesis that the cultivated peanut species possesses almost no molecular variability, we sequenced a diverse panel of twenty-two Arachis accessions representing Arachis hypogaea botanical classes, A-, B-, and K- genome diploids, a synthetic amphidiploid, and a tetraploid wild species. RNASeq was performed on pools of three tissues and de novo assembly wasperformed. Realignment of individual accession reads to transcripts of the cultivar OLin identified 306,820 bi-allelic SNPs. Among ten naturally occurring tetraploid accessions, 40,382 unique homozygous SNPs were identified in 14,719 contigs...

APETALA2 (AP2) belongs to the AP2/Ethylene Responsive Factor (ERF) family and regulates expression levels of downstream stress responsive genes as a transcription factor. In this study, we cloned six different isoforms of AhAP2 from peanut (Arachis hypogaea). Four isoforms (AhAP2.1, AhAP2.2, AhAP2.3 and AhAP2.4) had both AP2/ERF DNA binding domains and ERF-associated amphiphilic repression (EAR) motifs. Two isoforms (AhAP2.5 and AhAP2.6) only had an EAR suppressor domain. After agroinfiltration, AhAP2.1, AhAP2...

A series of alkyl bicarbamates supramolecular organogelators were synthesized with different structures and lengths of alkyl chains. The driving forces for the self-assembly of small molecules, including the intermolecular H bonding, π-π stacking and van der Waals interactions, played an important role in the formation of different 3D network structures, i.e., fibers, ribbons, sheets, and prisms. And a probable formation process of the gel networks was proposed. Furthermore, the phase-selective gelling performances were investigated for oil removal from aqueous solution...
